Determination of flash point - Pensky-Martens closed cup method (ISO 2719:2016)
ISO 2719:2016 describes three procedures, A, B and C, using the Pensky-Martens closed cup tester, for determining the flash point of combustible liquids, liquids with suspended solids, liquids that tend to form a surface film under the test conditions, biodiesel and other liquids in the temperature range of 40 °C to 370 °C.
CAUTION - For certain mixtures no flash point, as defined, is observed; instead a significant enlargement of the test flame (not halo effect) and a change in colour of the test flame from blue to yellowish-orange can occur. Continued heating can result in significant burning of vapours outside the test cup, and can be a potential fire hazard.
NOTE 1 Although, technically, kerosene with a flash point above 40 °C can be tested using this International Standard, it is standard practice to test kerosene according to ISO 13736.[5] Similarly, lubricating oils are normally tested according to ISO 2592[2].
Procedure A is applicable to distillate fuels (diesel, biodiesel blends, heating oil and turbine fuels), new and in-use lubricating oils, paints and varnishes, and other homogeneous liquids not included in the scope of Procedures B or C.
Procedure B is applicable to residual fuel oils, cutback residua, used lubricating oils, mixtures of liquids with solids, liquids that tend to form a surface film under test conditions or are of such kinematic viscosity that they are not uniformly heated under the stirring and heating conditions of Procedure A.
Procedure C is applicable to fatty acid methyl esters (FAME) as specified in specifications such as EN 14214[11] or ASTM D6751[13].
ISO 2719:2016 is not applicable to water-borne paints and varnishes.
NOTE 2 Water-borne paints and varnishes can be tested using ISO 3679[3]. Liquids containing traces of highly volatile materials can be tested using ISO 1523[1] or ISO 3679.
Bestimmung des Flammpunktes - Verfahren nach Pensky-Martens mit geschlossenem Tiegel (ISO 2719:2016)
Détermination du point d'éclair - Méthode Pensky-Martens en vase clos (ISO 2719:2016)
ISO 2719:2016 décrit trois méthodes, A, B, et C, pour la détermination du point d'éclair des liquides combustibles, des liquides contenant des matières solides en suspension, des liquides ayant tendance à former un film en surface dans les conditions d'essai, des biocarburants et d'autres liquides, au moyen de l'appareil d'essai Pensky-Martens en vase clos, dans la plage de température entre 40 °C et 370 °C.
ATTENTION ? Pour certains mélanges, aucun point d'éclair, tel que défini, n'est observé; à la place, il peut y avoir un élargissement significatif de la flamme d'essai (pas de phénomène de halo) et un changement de couleur de la flamme passant du bleu à l'orange jaunâtre. Le maintien du chauffage peut faire qu'une quantité significative de vapeurs soit brûlée à l'extérieur du vase d'essai, ce qui peut constituer un danger d'incendie.
NOTE 1 Techniquement les kérosènes ayant un point d'éclair supérieur à 40 °C peuvent être soumis à essai selon la présente Norme internationale. Cependant, il est d'usage courant de déterminer le point d'éclair des kérosènes selon l'ISO 13736[5]. De façon analogue, les huiles lubrifiantes sont normalement soumises à essai suivant l'ISO 2592[2].
La Méthode A est applicable aux distillats de pétrole (carburant diesel, mélanges de biocarburant, fioul domestique et turbocombustibles), aux huiles lubrifiantes neuves et en service, aux peintures et vernis, et à d'autres liquides homogènes ne faisant pas partie du champ d'application des Méthodes B ou C.
La Méthode B est applicable aux combustibles résiduels, aux résidus de bitumes fluidifiés, aux huiles lubrifiantes usagées, aux mélanges de liquides contenant des matières solides, aux liquides ayant tendance à former un film en surface dans les conditions d'essai ou ayant une viscosité cinématique telle qu'ils ne sont pas chauffés de manière uniforme sous agitation et dans les conditions de chauffage de la Méthode A.
La Méthode C est applicable aux esters méthyliques d'acides gras (EMAG) tels que définis dans des spécifications telles que l'EN 14214[11] ou l'ASTM D 6751[13].
La présente Norme internationale n'est pas applicable aux peintures et vernis renfermant de l'eau.
NOTE 2 Le point d'éclair des peintures et vernis renfermant de l'eau peut être déterminé suivant l'ISO 3679[3]. Les liquides contenant des traces de produits hautement volatils peuvent être analysés conformément à l'ISO 1523[1] ou l'ISO 3679.
Določevanje plamenišča - Metoda z zaprto posodo po Pensky-Martensu (ISO 2719:2016)
Ta mednarodni standard opisuje tri postopke, A, B in C, z uporabo testerja z zaprto posodo po Pensky-Martensu za ugotavljanje plamenišča gorljivih tekočin, tekočin, ki vsebujejo trdne delce, tekočin, pri katerih lahko v preskusnih pogojih nastane površinska plast, biodizla in drugih tekočin v temperaturnem razponu od 40 °C do 370 °C.
POZOR – Nekatere mešanice nimajo plamenišča, kot je opredeljeno; namesto tega lahko pride do znatnega povečanja preskusnega plamena (učinek brez sija) in spremembe v barvi preskusnega plamena iz modre v rumeno-oranžno. Stalno segrevanje lahko povzroči znatno gorenje hlapov zunaj preskusne posode in lahko pomeni nevarnost požara.
OPOMBA 1: Čeprav je z uporabo tega mednarodnega standarda praviloma mogoče preskusiti kerozin s plameniščem nad 40 °C, je ustaljena praksa preskušanje kerozina v skladu s standardom ISO 13736.[5] Podobno se mazalna olja preskušajo v skladu s standardom ISO 2592[2].
Postopek A se uporablja za destilatna goriva (dizel, mešanice biodizla, kurilno olje in gorivo za turbine), nova in rabljena mazalna olja, barve in lake ter druge homogene tekočine, ki niso zajete v postopku B ali C.
Postopek B se uporablja za težka kurilna olja, rezane ostanke, rabljena mazalna olja, mešanice tekočin s trdnimi delci, tekočin, pri katerih lahko v preskusnih pogojih nastane površinska plast, oziroma tekočin s takšno kinematično viskoznostjo, ki ne omogoča enotnega segrevanja v pogojih mešanja in segrevanja iz postopka A.
Postopek C se uporablja za metilne estre maščobnih kislin (FAME), kot je določeno v specifikacijah, npr.
EN 14214[11] ali ASTM D6751[13].
Ta mednarodni standard se ne uporablja za barve in lake na vodni osnovi.
OPOMBA 2: Barve in laki na vodni osnovi se lahko preskusijo z uporabo standarda ISO 3679[3]. Tekočine, ki vsebujejo sledi zelo vnetljivih materialov, se lahko preskusijo z uporabo standarda ISO 1523[1] ali ISO 3679.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents sho
